 acute. Petiole from above about 1| times as long as broad, broader 

 behind than in front; in profile as high as long, with angularly 

 pointed node, its anterior slope concave, its posterior slope straight. 

 Postpetiole broader than long, broader than the petiole and some- 

 what broader in front than behind, dentate anteriorly on the 

 ventral side. Gaster and legs as in lecp. 



Mandibles shining, finely and very sparsely punctate; head, 

 thorax, petiole and postpetiole subopaque evenly reticulate-rugose, 

 the head in front and on the sides longitudinally rugose, the scrobes 

 shining and finely, transversely rugulose. Gaster shining, covered 

 with rather strong, transverse piligerous punctures. Antennal 

 scapes very finely rugulose; legs smooth, sparsely and finely punc- 

 tate. ' 



Hairs yellowish gray, appearing blackish in some lights, mod-

 body, shorter and more oblique on the legs, reduced to pubescence 

 on the antennae.

Described from twenty-one specimens, comprising nearly an 

 entire colony, taken from a small cavity in a rotten log in the dark 

 tropical "scrub" at Kuranda, Queensland. In life these ants are 

 sluggish and timid, like the species of Podomyrma. The latter, 

 however, nest in the trunks and branches of living trees and move 

 about in the sunlight.
